— We investigate the decoding region for Algebraic Soft-Decision Decoding (ASD) of Reed-Solomon codes in a discrete, memoryless, additive-noise channel. An expression is derived for the error correction radius within which the soft-decision decoder produces a list that contains the transmitted codeword. The error radius for ASD is shown to be larger than(More)
We bound the probability of error of Algebraic Soft-Decision Decoding (ASD) of Reed-Solomon codes in a discrete, memoryless, additive-noise channel. First, we derive an exponential error bound on the probability of list-decoding error that improves on the bound presented in [9]. However, our previous work [1] has shown that list-decoding error is not(More)
We investigate the decoding region for algebraic soft-decision decoding (ASD) of Reed-Solomon (RS) codes in a discrete, memoryless, additive-noise channel. An expression is derived for the error correction radius within which the soft-decision decoder produces a list that contains the transmitted codeword. The error radius for ASD is shown to be larger than(More)
BACKGROUND The efficacy of antibiotics in preventing surgical site infections (SSIs) depends on the timing of administration relative to the start of surgery. However, currently, both the timing of and recommendations for administration vary substantially. AIM To determine how the economic value from the hospital perspective of preoperative antibiotics(More)
One advantage of a research university is the opportunity that it provides for undergraduate students to become involved in cutting edge research with leading scientists and engineers. The University of Pittsburgh and its Swanson School of Engineering are no different. This past spring, with the generous support of the Office of the Provost, the Swanson(More)

OBJECTIVE To estimate the economic value of dispensing preoperative home-based chlorhexidine bathing cloth kits to orthopedic patients to prevent surgical site infection (SSI). METHODS A stochastic decision-analytic computer simulation model was developed from the hospital's perspective depicting the decision of whether to dispense the kits preoperatively(More)
